godot/scene/gui/file_dialog.h
Dmitry Koteroff e3b0214f40 A few small adjustments to file dialogs:
a) Added Backspace key support for Tree-based file dialog.
b) Fixed issue inability to select a folder in project manager (always previous folder was selected instead).
c) Open Directory mode: changed "Open" to "Select Current Folder"
d) Block "Open" button when inappropriate content is selected (for example, file when in open folder mode, or folder when in open files mode)
